a force that holds groups of two or more atoms together and makes them function as a unit is a _____________

the energy required to break a bond is called the ______________

Na+ Cl- (sodium chloride) is an example of ___________, which is a bonding of oppositely charged ions (i.e. metals with non-metals)

ionic substances are formed when an atom that loses electrons relatively easily reacts with an atom that has a high affinity for electrons is called an ____

The type of bonding where electrons are shared by nuclei in the space between is called ___________ (H-H)

A type of bonding where the electrons cannot be shared equally but cannot be removed is __________ (H+ -- F-)

the relative ability of an atom in a molecule to attract shared electrons to itself is called ___________________ (Fr =0.7, F=4.0)

a molecule that has a center of positive charge and a center of negative charge is said to have a _____________ (H--F)

Atoms in stable compounds will almost always have a ___________ electron configuration. (i.e. All outer orbitals are full!)

The ______________ is a representation of a molecule that shows how the cadence electrons are arranged among the atoms in the molecule

Hydrogen forms stable molecules where it shares two electrons. that is, it is following a ________ rule

Period 2 non-metals (O, N, F, etc) are stable when they have enough electrons to fill out the outer orbitals (2s, 2p); they follow the _______ rule

The pair of electrons shared with another molecule are called ________ pairs, while the other pairs of electrons that aren't shared are called lone/unshared pairs.

a __________ bond involves two atoms sharing one electron pair. A _________ bond involves two atoms sharing two pairs of electrons

a molecule shows __________ when more than one Lewis structure can be drawn for the molecule.

the 3-d arrangement of the atoms in a molecule are called ___________

some molecules form a ___________, where all atoms are in a line. (180 degree bond)

a molecular structure where all 4 atoms are in the same plane with 120 degree bond angles is called a ____________

a bent or "v shaped" bond describes the structure of a molecule. this is called the __________

a type of molecular structure, a ______ has four identical triangular faces along the bond angles.

a model used in predicting the molecular structure (in nonmetals): the structure around around a given atom is determined by minimizing repulsions between electron pairs. (bond & nonbonding pairs of electrons are positioned as far apart as possible)

molecular structure where one side is different from the other 3 sides is called a _____________
